Casein-Based Labeling Adhesives are zinc- and borax-free.

Eticol labeling adhesives are based on natural polymers obtained from casein, minimizing wastewater produced by bottlers and maximizing shelf life and quality of products. Flexible, water-based bottle labels maintain bond on moist and cold surfaces and also in presence of condensation on glass. They are available in variants with high wet tack and ice-water resistance, and can be used with high-speed labeling machines.
